Thanks for sharing @user1037. This sounds very similar to what @Notearsformula is facing in his post here: Grieving and Crying
I get what you mean about being a stoic. I’m kinda like one too and my partner also feels that I’ve not been adequately meeting her emotional needs - and by then I mean showing wayyyyy emotions. Otherwise she feels like she’s talking to a wall.
I don’t have much concrete advice but I’m starting by describing my feelings a lot more. Expanding your emotions vocab helps too so you can accurately describe how you’re feeling. Then as you learn more, maybe you’ll find certain words that associate with you better and maybe feel more intense feelings?
